Tennis elbow

Common card · No. 218596

Tennis elbow, also known as lateral epicondylitis, is an enthesopathy (attachment point disease) of the origin of the extensor carpi radialis brevis on the lateral epicondyle. It causes pain and tenderness over the lateral epicondyle. Tennis elbow is idiopathic, meaning its precise cause is unknown. It likely involves tendinosis, an overuse injury of the local tendon. It is typically associated with work or sports – classically racquet sports (including paddle sports) – but many people with the condition are not participants in these activities. The diagnosis is based on the symptoms and examination. Medical imaging is not commonly used. Untreated enthesopathy usually resolves in 1–2 years. Treating the symptoms and pain involves medications such as NSAIDs or acetaminophen, a wrist brace, or a strap over the upper forearm. Corticosteroid injections as treatment are not common.
